RF transistor model

I search model for Rf transistors but the only model i could find are S-parameters based.
But these model are not taking in account the non linearities and the time response of the device.

I there any spice model existing for RF transistor (ex eudyna, philips ...)

Thanks.

There are a lot of RF transistor spice models. You should be more specific, what do you need?

To be more precise, i think about of FLK207XV from eudyna (ex fujitsu): it is a power GaAs FET.

Where coud i find model libraries for GaAs FET power transistor , eudyna or other manufacturers , never mind ?

Thanks.

A few links:

Some of them are part of the datasheet, in pdf format. You have to pick-up from there and put in the format that you are looking for.

There is a SPICE model of FLK207XV in this document on page 6 and 8:
